WALL FORM Filed April 10f, 1922 INVENTOR JAarsrad 8y r61 ATTORNEYS of Chicago,.in the county of Cook and State of Illinois, have invented a new and useful Improvement in Wall Forms, of which the following is a full, clear, and exact description.

My invention relates to improvements in wall forms, and it consists in the combinations, constructions, and arrangements herein described and claimed.

"An objectof my invention is to provide "a wall form which is adapted to be used fora form for the lower portion of a wa ll, and to then be removed therefrom. and be placed on the top 'of the wall thus built,

and be used for another form. r

A further object of my invention is to provide a device of the character described which is adapted to build concrete walls having a novel exterior, such as walls resembling a series of logs for a log cabin, or a wallresembling a series of tiles for a tiled house.

A further object of' myinvention is to provide a device of the character described which. is simple in construction and which can be readily removed from the wall portion made and be secured to the top of the wall portion.

A further object of my inventioiristo provide a device of the character described in which the forms are of novel construction. and are interchangeable.

Other objects and advantages will appear in the following specification, and the novel features of the invention will be particularly pointed out in the appended claim.

My invention is illustrated in the accompanying drawings, forming part of this application, in which Figure 1 is an end elevation of the device as shown applied to a wall,

Figure 2 is a plan view of the device,

Figure 3 is a side elevation of'a wall form showing the reenforcing ribs,

Figure 4 is a section along the line l--4 of Figure 1,

Figure 5 is a modified form of the wall form,

Figure 6 is another modified form of a wall form, and

Figure 7 is a wall. form used for the ends or corners of buildings or the like.

In carrying out my invention, I provide 1,510,082 PATENT OFFICE.

FORM.

a wall form 1 of the shape shown in Fig ures 1 and 3. This form is provided with longitudinally extending arcuate-shaped recesses which in reality form a series of corrugations in the Wall form. As clearly shown in Figure 3, the form is preferably rectangular, although it may be any other shape desired without. departing from the spirit and scope of my'invention. The side '2 which contacts with the cement 3 or a like self-hardening material, 15 reenforced bv ribs t. .These ribs extend at right angles to each other and terminate at the sides 5 of the form. The form 1 has bolt openings 6 therein and the sides 5 have bolt openings 7 therein. 'From this construction it will be apparent that a series of wall forms 1 may be securedto each other by inserting bolts through the alined openings 7 of adjacent sides.

The forms 1 are spaced from each other and have their sides 2 disposed opposite each other. The forms. are held in this position by means of U-shaped frames 8. The. construction of the frames 8 is clearly illustrated in Figures 1, 2, and 4. of the drawings. One of these frames is disposed adjacent to each end of the forms 1. The frame comprises three angle irons formed into the shape shown in Figure 1. each. of the corners of the frame and is secured in place by a rivet 10 (see Figure l).

The plate 9 extendsdownwardy along the sides of the U-shaped frame 8 and carries a transverse angle iron or bar 11 at its lower end. This bar 11 is secured to the plates 9 by means of rivets 12 or the like. The bar 11 is disposed in the same plane as the tops of the forms 1.

From the foregoing description of the various parts of the device, the operation thereof may be readily understood. In

building a wall of concrete or the like, a form. having any distinctive pattern in its side 2 may be used, this pattern being of any shape desired such as the log type shown in Figure 6, or the til-ed type, as shown in Figure It is obvious that many other forms of different designs may be used, but these two are given as a specific example of two of the forms. The principal object is to provide forms which. may be removed from the portion of the wall built and be disposed on the top of the built portion,

w hereby an additional portion. may be built onto the lower portion. The forms are dis- A plate 9 is disposed in posed the desired distance apart and are secured to each other by the frames 8. As heretofore stated, as many of these forms as desired may be bolted together so as to form a Wall of any desired length. The concrete or other like self-hardening ceme-ntitious material is then poured between the forms and is left to harden. After the cement has set, the forms are removed from the wall portion by means of first removing the frames 8. It will be observed that the lower ends of the forms shown in Figure 1 are curved outwardly so as to rest on top of the wall 3 which has previously been made. It is obvious that if the forms 1 are prevented from moving outwardly,'that they will be held in place since the curvature of the sides of the wall 8 prevents any downward movement of the forms with respect to the wall. As a. means for further locking the forms in place after they'have been disposed on top of the wall portion already built, I dispose bolts 13 in the openings 16, these bolts extending through the legs of the frame 8 and holding the forms in adjusted position. As heretofore stated, the member 11, prevents the tops of the forms 1 from moving outwardly. The bolts 13 also act as a support to the forms 1 so as to prevent the forms from moving downwardly. An ad ditional amount ofconcrete may now be poured between the forms and will be contained between the sides 2 of the forms and the top of the wall 3 already built. This cement can be left to harden in the same manner as heretofore described. When the cement has hardened, the forms may again be removed and be applied to the top of the portion of the wall just made. In this manner, the wall may be extended to any height desired. It will be obvious that the outer curvatures of the walls not only add a distinctive feature to the walls, but also aid in supporting the forms when a new addition is built to the wall. It is obvious that houses made of concrete may have walls of various forms, such as walls resembling log walls, walls resembling the tiled walls, or the like.

In Figure 7 I have shown a. form 13 ap plied to the corners of two walls which have been made with a form having a log design therein. To further carry out the effect of a wall built of logs, this end form is constructed so as to permit slight cylindrical projections which are in ulinement with the rounded sides of the logs. In this manner, the house or the like, built with a log form of wall. will also have the logs projtxwting from the corners in a realistic style. It is obvious therefore that. houses of very distinctive pattern may be made with no addition in cost to the construction of the walls of the house, since the forms used are so fashioned as to give the desired finish to the house. As heretofore stated, the forms are interchangeable and are readily secured in place. It will therefore be apparent that a wall may be put up in the minimum amount of time and with the minimum amount of labor.

I claim:

A wall form comprising a frame for bolding wall forms in position on the wall, said frame consisting of U-shaped members constructed of angle irons, the vcrtices of said irons being disposed on the outer side of the frame, rcenforeing plates disposed at the bend inv the said U-shaped member, a bar connecting said plates together, bolts connecting the free ends of each frame together, wall forms having openings adapted to receive said bolts whereby said wall forms are support-ed in adjusted position on the wall, the tops of said forms bearing against the bar whereby they are prevented from swinging inwardly.
